Setting Group 2 – Logic Statements
When setting group 2 becomes active either through a setting group change or
is the default group after relay power up, ProLogic 9 becomes high after the
10.00 second delay, if external input one is low. The example shows ProLogic
9 set for a 0.26 second dropout time to be used with ProLogic 10 dropout timer
allowing for the slower processing thread where Group Logic is processed and
providing a definite timed pulse to the group logic.
Figure L.4: ProLogic 9
Prologic 10 has no intentional delay and becomes high for the combined drop-
out time of ProLogic 9 and 10 equalling 0.52 seconds.
Figure L.5: ProLogic 10
Group Logic 1 is used to switch to the new setting group; there is no intentional
delay.
